MRI findings of a 14-year-old boy with subdural empyema (SE) are reported and compared with those of serial CT-scan. He was admitted with fever, headache, right hemiplegia and facial palsy. Initial enhanced CT-scan revealed a slit left lateral ventricle and a shift in the mid-line structures, but failed to detect any SE. MRI at 10 days after admission clearly demonstrated SE as an area of low intensity on T1-weight (T1WI) and very high intensity on T2-weight (T2WI). Post-contrast enhanced MRI (CE-MRI), using Gd-DTPA, showed a contrast enhancement in the wall of SE. However, no definite parenchymal abnormal intensity areas were detected, suggesting that the diagnosis was made sufficiently early for timely treatment and good neurological outcome. CE-MRI proved to be a more powerful and better diagnostic procedure than enhanced CT-scan, and was very useful in determining the state and development of the disease.
报告了一名14岁患有硬膜下积脓（SE）男孩的MRI检查结果，并与系列CT扫描结果进行了比较。他因发热、头痛、右侧偏瘫和面瘫入院。最初的增强CT扫描显示左侧侧脑室变窄和中线结构移位，但未检测到任何硬膜下积脓。入院10天后的MRI清楚地显示硬膜下积脓在T1加权像（T1WI）上为低强度区域，在T2加权像（T2WI）上为非常高强度区域。使用钆喷酸葡胺（Gd-DTPA）的对比增强MRI（CE-MRI）显示硬膜下积脓壁有对比增强。然而，未检测到明确的实质异常强度区域，这表明诊断足够早，以便及时治疗并获得良好的神经学结果。CE-MRI被证明是一种比增强CT扫描更强大、更好的诊断方法，在确定疾病状态和发展方面非常有用。
